Abstract
An intermediate station receives device Random Access Channel (RACH) transmissions from a plurality of machine type communication (MTC) devices and transmits at a bulk RACH transmission to a base station where the bulk RACH transmission represents the RACH transmissions from at least two of the device RACH transmissions.
Claims16
An intermediate station comprising:
- a receiver configured to receive a first machine type communication (MTC) Random Access Channel (RACH) transmission from a first MTC device and to receive a second MTC RACH transmission from a second MTC device;
- a transmitter configured to transmit a bulk RACH transmission to a base station, the bulk RACH transmission representing the first MTC RACH transmission and the second MTC RACH transmission, wherein the bulk RACH transmission has a cyclically shifted Zadoff-Chu sequence indicating the bulk RACH transmission has been transmitted by a RACH aggregator and represents a plurality of RACHs from multiple MTC devices.
A wireless communication system comprising:
- a first intermediate station comprising:
- a first receiver configured to receive a first machine type communication (MTC) Random Access Channel (RACH) transmission from a first MTC device and to receive a second MTC RACH transmission from a second MTC device, the first MTC device and the second MTC device within a first intermediate station geographical service area;
- and
- a first transmitter configured to transmit a first bulk RACH transmission to a base station, the first bulk RACH transmission representing the first MTC RACH transmission and the second MTC RACH transmission, wherein the first bulk RACH transmission has a first cyclically shifted Zadoff-Chu sequence indicating the first bulk RACH transmission has been transmitted by a RACH aggregator and represents a plurality of RACHs from multiple MTC devices;
- and
- a second intermediate station comprising:
- a second receiver configured to receive a third MTC RACH transmission from a third MTC device and to receive a fourth MTC RACH transmission from a fourth MTC device, the third MTC device and the fourth MTC device within a second intermediate station geographical service area;
- and
- a second transmitter configured to transmit a second bulk RACH transmission to the base station, the second bulk RACH transmission representing the third MTC RACH transmission and the fourth MTC RACH transmission, wherein the second bulk RACH transmission has a second cyclically shifted Zadoff-Chu sequence indicating the second bulk RACH transmission has been transmitted by a RACH aggregator and represents a plurality of RACHs from multiple MTC devices, the same communication resources assigned for MTC RACH transmission within the first intermediate station geographical service area and the second intermediate station geographical service area.
